The stop also controls the height and width of the locked window and can be mounted for single or double hung and sliding windows. This window stop meets ASTM standards.

You literally hold the hinge open from frame to window as it tries to spring closed. While doing so you screw it in. The soft plastic shreds from the screws and the long screws hit the hard wood beam and will not go flush with the frame. That aside, once installed it’s the most safe and effective I’ve found. I feel safer with two per window, one left and one right, but that’s your call as it will make it much harder to disengage if you ever needed to. If you are doing multiple windows I mark 4 inches on the packaging and walk around with that to avoid constantly rechecking the measurements.

My husband had these installed within an hour of receiving them, and we had guests! Hubby tends to procrastinate, but these were so easy to install and so very needed that he just drilled the pilot holes and attached the locks. Easy peasy! It's been almost a week and so far the 2-year-old hasn't figured them out. She can unlatch the other two locks on our vinyl windows, but she hasn't bothered with this one. I'm hopeful it will last awhile, as our split-level home has an upper level living room with low windows. Oh, and they're easy enough for anybody else to open if we do need to open the window farther for some reason. So far, very pleased with this purchase and would buy again.

I have an over hundred years old home with big heavy wood windows so this is not going hold them open and not needed to keep closed as an adult has a hard time opening. They are spring loaded and difficult to hold clip back so to open heavy wooden window.

Worked perfectly. I wanted this so I could limit how far the bathroom window could be opened because I like to leave it open slightly when I leave my house for the day but didn't want it not to be secure because of where it is located and it worked perfectly for that purpose. Now I can leave it open 1" but it won't open any further unless you release it so it's not enough that someone could break into my house through this window but it is enough to allow me to leave it open to vent my bathroom after a shower in the morning and leaving for work for the day. Also doubles as a child safety to keep kids from being able to open the window too far which is nice.
